CALENDAR-CLOCK.

SPECIFICATION forming part of Letters Patent No. 527,386, dated October9, 1894.

Application 'lle October 12,1893.

To all whom it may concern:

Be it known that I, CHARLES W. FEIsH- TINGER, a citizen of the UnitedStates, residing at Fritztown, in the county of Berks, State ofPennsylvania, have invented certain Improvements in Calendar-Clocks, ofwhich the following is a specification.

My invention relates to calendar clocks and my main object is to providea simple and positive calendar mechanism which will permit the propersetting of either the date, month or year wheels entirely independentlyof each other.

The setting of the year, month, and date is ordinarily quite troublesomeeven to an expert, owing mainly to the fact'that the several parts areso connected as to be incapable of separate adjustment. I have overcomethis objection by providing aconstruction in which the year, month, andday of the month wheel are each adjustable independently of the others,yet which when properly set are automatically operated by very simpleand effective mechanism.

Figure l is a rear view of a complete calendar mechanism involving myinvention the operating connection to the clock mechanism being alsoindicated. The rear plate of the calendar mechanism is removed and theparts are represented in proper position for making the leap yearmovement from February 28 to March 1, the dials however not being shown.Fig. 2 is apartial edge view showing therelative positions of the date,month, and year wheels. Fig. 3 is a partial view similar to Fig. 1,showing the position of the parts after the movement referred to hasbeen made and before the return of the pushing lever to its normalposition. Figs. 4, 5, 6, and 7 are separate views of several parts.

No portion of the clock movement is shown except a wheel E from whichthe calendar movement is effected as will be described later. Thecalendar mechanism may be attached to the inner face of the door belowthe clock face so as to be swung out of connection with the operatingrod D from the clock movement, and permit convenient access.

A representsthe day-of-the-month or date wheel which has thirty-oneteeth and a central arbor A to the forward end of which a pointer may beattached.

Serial No. 487,974. (No model.)

B is the month of the year wheel provided with twelve notches of depthsvarying with the number of days in the several months,

the notches b for the thirty-day months being twice as deep as thenotches b' for the thirty-one day months, and the single notch b2 forthe month of February being four times as deep as b. Its hollow arbor Bis mounted upon'the arbor of the date wheel and may also be providedwith a pointer at its outer end or arranged to operate a month dial orroll as preferred.

P and P are the front and rear plates of the calendar frame, the formerbeing adapted to serve as a dial plate if desired.

The day of the week may be indicated by a roll M operated in anyordinary manner from the clock movement and forms no part of myinvention..

The day of the month wheel lever C is pivoted to a fixed point c3 andconnected in any suitable lnanner to an operating rod D suspended fromthe clock movement. To the arm c of this lever is connected a pallet Cthrough which the daily movement of the day of the month wheel iseffected by the lifting of the lever. A rock arm F which is pivoted at afixed point j", carries at its upper t end F' a push lever H for makingthe necessary movements at the end of each month. This lever H isprovided with a toe h which engages and rides upon the notched peripheryof the month of the year wheel, and with a heel h3 which is arranged toengage a projection a on the face of the day of the month wheel when thelever is allowed to drop sufticiently to do so. This dropping movementof the lever is controlled in the first place by the depth of thenotches in the month wheel and in the second place, for the month ofFebruary, by the leap year Wheel L the @dect of which will be describedlater. The pushing movement is controlled by alocking arm K which ispivoted at one end to a fixed point lo and is normally supported at theother on the end of the push lever by means of a hanger vprojection lawhich also serves to prevent any pushing movement of the lever H by itscontact with a shoulder h2 on the top edge of the latter. In order torelease the lever and permit the required pushing movement at the end ofeach month a IOO cam or incline a is provided on the face of the datewheel and is so arranged as to engage the heel k2 of the locking arm andraise it above the shoulder h2 at the proper time.

The pushing movement of the lever H is eected by the rock arm F which ispreferably arranged as shown so as to make the movement positive. At apoint f at the lower end of the rock arm is pivoted a trigger G the headg of which is held outside of the swing of the date wheel lever C solong as the lock arm K engages the shoulder 71.2 of the push lever; butwhenever the latter is released the action of the spring I pushingagainst the arm g of the trigger moves the rock arm sufficiently tothrow the trigger-head g in the path of the ledge c2 on the date wheelleven-the arm g2 of the trigger being fu1- crumed on a lixed pin p. Withthe trigger in this position the upward movement of the lever Cpositively swings the rock arm F and moves the push lever H. The ledgec2 also projects sidewise so as to come in contact with the rock arm Fand swing the latter slightly downward with each downward movement ofthe lever C, the eifect of this being to slightly retract the push leverH, so as to free the stop 7c of the locking arm from contact with theshoulder h2 so that the lock ing arm may be raised when it comes incontact with the cam ct without danger of the pushing lever remainingraised with it.

The year wheel L is provided with four teeth Z and is mounted in theplate P close to the month wheel and directly below the end of thepushing lever H so that the toe 7L of the latter may overhang it; andthe periphery of the wheel except where extended at lis arranged to belevel with the bottom of the February notch b2 of the month wheel whilesaid extended portion Z is adapted to extend above the bottom of thenotch when in leap year position as indicated in Fig. 1. A pointer andleap year dial as shown in Fig. 7 are also provided.

The wheel E from which the calendar movement is derived makes onerevolution every twenty four hours. The lever D from which the operatingrod D is suspended is pivoted at d2 and is raised by the pin e on thewheel engaging the hooked arm d of the lever. It is preferablycounterbalanced and the downward movement is effected positively by thepin e on the wheel coming in contact with the projection d of the lever.

The operation is as follows: To set the calendar merely turn thedifferent pointers separately to the required month, day of the month,and year. As shown in Fig. lit is set for February 28 of a leap year andthe push lever I-I, with the lock lever resting upon it, has droppedonly upon the extension Z of the year wheel instead of dropping to thebottom of the notch b2 as in an ordinary year. The cam a on the datewheel has been moved into contact with the heel k2 and the next upwardmovement of the lever C which moves the date wheel to the 29th. willlift the rock arm K. The lever Il is likely to be lifted with it owingto the pressure against the shoulder h2 but the downward movement of thelever C draws the lever H back momentarily so as to release it and causeit to drop under the stop 7c. The spring I then presses the head g ofthe trigger G into the path of the lever C ready for the next upwardmovement of the latter. Vhen this takes place on the night of the 29th.the rock arm F is positively raised with the lever O thus pushing theleve.l H into the position indicated in Fig. 2. This movement of thelever H has not only carried the month of the year wheel forward toMarch but by coming in contact with the projection ct on the date wheelhas moved the latter the required distance to indicate the 1st of themonth. The next downward movement of the rod D draws the lever II backto its normal position with the lock arm resting upon it and ready tooperate in a similar manner upon the March notch of the month of theyear wheel when the cam or incline a shall have again come around andreleased it, which will occur later owing to the higher position of theheel 7a2 with relation to the cam. In making the movement from December3l to January l a projection b5 on the month wheel is arranged to comein contact with the teeth of the year wheel L and to turn the latter aquarter turn thus placing it automaticallyin proper position for thenext February movement.

The radical dierence between my machine and those heretofore devisedconsists in the arrangement of the indicator wheels so that each can bemoved to indicate any desired figure on its own dial without changingthe other. The day-of-the-month wheel can be turned any number of timeswithout affecting the month-of-the-year wheel and vice versa; also theleap year wheel can be turned freely without moving the month-of-theyearwheel. Each dial is set without regard to the others, to the desiredfigures and then each is properly moved by the direct action of theclock.

It is obvious that the details and arrangement of the describedconstruction may be greatly varied without departing from the spirit ofmy invention. I have for instance arranged the spring I so as to make iteffect directly the movement of the pushing lever but prefer to makethis movement positive as described. I do not therefore wish to limitmyself to the particular construction shown; but

What I claim is l. In a calendar clock mechanism the combination withindependently rotatable day of the month, month of the year, and leapyear wheels, of mechanism substantially as described for automaticallyand jointly operating said wheels while permitting independent settingof the same, substantially as set forth.
